I had this with dd - they were monitoring her growth and at 38 weeks saw that I had lost a lot of amniotic fluid and poor dopplers.... dd was born by emergency caesar that morning - but was not affected by the lack of fluid... they will just be monitoring the baby's blood sugar levels etc in special care - should just be in an egg box like all babes are rather than a humidicrib etc - from my recollection of baby in special care with dd....
have a friend who has just had her first - very low fluid levels throughout the pregnancy - from what I have heard ( she in in the UK) baby born by caesar ( at term) and all looks fine.
As zebra says if they were worried they would have had the cs today.... I had my scan at 9.30 and dd was born at 11.04 by caesar....
They are also monitoring her and have kept her in so I am sure it will all be well.
